While makeing $ cd /usr/pkgsrc/emulators/suse100_base ( 
suse_base-10.0nb5 ), I got a checksum error on glibc-2.3.5-40.i586.rpm.

I am running bsd 4.99.31, current from 10-06-2007.

I think one of the distribution sites has a bad distribution.

I googled for other sites and found http://rpm.pbone.net/.  One of the 
mirrors had what I needed:

http://rpm.pbone.net/index.php3/stat/4/idpl/3705031/com/glibc-2.3.5-40.i586.rpm.html

Everything built fine after that.
